reflected both on screen and in print, follow these steps.
1. Press the Menu key .
2. Choose Spirometry Settings > Operation Settings.
The following screen appears.
Figure 2. “Spirometry Operation Settings” Screen
3. If desired, change the settings.
Setting Description
Select Protocol The selected protocol determines the way the spirometer operates when testing a patient.
Applicable for FVC testing only. For details, see
“Spirometry Protocols” on page 55.
• None
• PCP (primary care practitioner)
• NIOSH
• OSHA
• SSD (Social Security & Disability)
Select Adult
Predictive Norm The selected adult norm is the primary source of predictive values for adult patients.
For details, see
“Norm Profiles” on page 66.
Select Ped.
Predictive Norm The selected pediatric norm is the primary source of predictive values for pediatric patients.
For details, see
“Norm Profiles” on page 66.
Select Best Effort
Formula A patient’s best effort is a measurement calculated from a set of efforts. To determine the
way in which best effort is calculated, choose from these options:
• Best Measurement —
Defines best effort as the single best effort in a set of efforts (best FVC-pre, best FVC-
post, best SVC). This ATS-recommended method uses the effort with the highest sum
of FVC + FEV1, or the effort with the highest SVC value. (For details, see the document
noted in
Reference 6 on page 75.)
• Best Composite —
Defines best effort as a composite of the highest parameter values across all selected
efforts (except FVC and FEV1, which are both selected from the highest sum of
FVC + FEV1.)
